Hi,
First let me state that this is an opinion based upon my experience with the dark armor set. I disagree with the OP overall conclusion about survivability given how OG and CoF work, and stipulate that Fury issue has already been refuted. Is fury delayed with OG and CoF? Maybe. I have gone into mobs with them down just to get the Fury bar up, then toggled them on followed by Dark Regen to heal the damage I just endured.
Experience:
39 month player with 7 50s
First DA toon was a brute, DM/DA.
Second DA toon was a scrapper, Spines/DA
Both are level 50.
Experiences with survivability:
Before OG, sucked.
After OG, OMG! What a difference. And IMHO you cannot argue survivability without considering this power. A comparison that leaves this out (irrespective of fury) is fundamentally flawed.
Cloak of fear ugh the end cost
I do hope people who do run this are using it more for accuracy debuff. I only run it on my scrapper who went to the trouble of getting enough IOs to improve recovery so that I could run both OG and CoF as much as I wanted to constantly. I am now considering getting IOs for this for my Brute, but the cost red side is so intimidating.
Finally, let me say that I really enjoyed reading the OPs post and thank them for the time and effort that went into writing it. I disagree with your conclusions about survivability and acknowledge your point concerning delayed fury building. But I would like to see the Devs back off the end cost of CoF and the accuracy penalty somewhat. I also would like to see a decrease in the end cost of Dark Regeneration. Why should it be such an end hog when it needs an accuracy check unlike other brute heal powers?
I apologize for the double post, first one went awry.
